Question

Classify the following solids into different types : 1) plastic 2) P4 molecule 3) S8 molecule 4) iodine molecule 5) Tera phosphorous decoxide 6) ammonium phosphate 7) brass 8) rubidium 9) graphite 10) diamond 11) NaCl 12)silicon

Answer 1

PLASTIC - COVALENT SOLID
P4 MOLECULE- MOLECULAR SOLID
S8 MOLECULE- MOLECULAR SOLID
IODINE MOLECULE - MOLECULAR SOLID
TERA PHOSPHOROUS DECOXIDE - MOLECULAR SOLID
AMMONIUM PHOSPHATE - IONIC SOLID
BRASS - METALLIC SOLID
RUBIDIUM - METALLIC SOLID
GRAPHITE - COVALENT SOLID
NACL- IONIC SOLID
DIOMAND - COVALENT SOLID
SILICON - COVALENT SOLID

Answer 2

"The rigid state of the substance is called solid. The arrangement of an atom in solid can be divided into two categories namely crystalline solids and amorphous solids.

The arrangement of atoms and bonding between atoms in solids are again divided into four namely metallic solids, molecular solids, network solids, and crystalline solids.

Classification of the following substances are as follows.

1. Plastic  - solid (covalent)
2. P4 molecule - solid (molecular)
3. S8 molecule - solid (molecular)
4. Iodine molecule - solid (molecular)
5. Tera phosphorous decoxide - solid (molecular)
6. Ammonium phosphate - solid (ionic)
7. Brass - solid (metallic)
8. Rubidium - solid (metallic)
9. Graphite - solid (covalent)
10. Diamond - solid (covalent)
11. NaCl - solid (ionic)
12. Silicon - solid (covalent)"
